How to cancel Kviku by mail
Collect the details you need
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Kviku is only as good as the details it quotes.
Write your request
Kviku is based in Spain, so the letter goes out in Spanish, built from our Spanish template. Subject line: “Asunto: Solicitud de cancelación – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post it with proof of delivery
Send the letter to the Alicante mailing address shown below by certified mail. Keep the tracking number safe.
Hold on to the receipt
Delivery confirmation is your evidence that Kviku was asked. Watch the next statement or two for any further Kviku charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Kviku cancellation letter goes
Kviku lists Avenida Perfecto Palacio de la Fuente 1, oficina 411, 03001 Alicante, Spain as its mailing address.
Postal code 03001 places the address in Alicante, Spain.
The letter greets the reader with “A quien corresponda,”; your own details sit under the labels Titular de la cuenta, Dirección de facturación registrada and Correo electrónico registrado.
Prefer to write it yourself? Use our letter template
Before you cancel Kviku, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
